FUEL-ECONOMIZING VALVE.

To all whom it may concern:

Be it known that I, WALTER J. KENNEDY, a citizen of the United States,and resident of Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Fuel- FiconomizingValve, of which I hereby declare the following to be a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

The objects of the invention are to provide an automatical gravitycontrolled valve which will prevent foods from burning and which willalso prevent the waste of gas when the cooking utensils are removed fromthe stove. I V

The invention comprises the pressure operatedvalve and the detailconstruction of the various parts and operating devices hereinafterdescribed, shown in the accompanying drawings and specifically pointedout in the claims.

In the accompanying drawings Figure 1 is a plan view of a stove andburner showing the valve and means for operating the same; Fig. 2 is arear elevation of the stove showing the valve operated by means of akettle placed over the valve operating device; Fig. 3 is a horizontalsection of the valve; Fig. 4 is an enlarged portion thereof; Fig. 5 is atransverse section on line aa Fig. 3; Fig. 6 is a side elevation of thearm which operates the valve showing the uni versal adjustment therefor;Fig. 7 is a transverse section thereof; Fig. 8 is an end view of thedivided ball collar therefor; Fig. 9 is a view of the inner face of oneof the divisions of said collar; Figs. 10, 11, 12, and 13 show modifiedadjusting means for the valve arm; Fig. 14 is a vertical section of amodifled form of valve showing the universally adjustable arm therefor;Fig. 15 is an edge view of the fixed disk shown in Fig. 3; Fig. 16 is anedge view of the rotatable. disk shown in Figs. 3 and 5. V

' In these views 1 is a valve casing, 2 is the inlet pipe for gasleading thereto, 3 is the inlet pipe leading therefrom to the burner 4L.5 is a simple out off valve in the casing. 6, and 7 Fig. 3 are valvedisks one of which 6 is rotatable to admit and cut ofi' the gas flowingthrough the casing. The other one 7 is fixed and the disks are providedwith registering perforations P, P.

8 is a rod provided with a finger, 9, which Specification of LettersPatent.

engages the rotatable disk. This rod is elbow shaped and turned downwardand at its extremity is provided with anarm 10 that extends above theburner and is provided wlth the spreading downwardly turned fingers 11,which are normally elevated above the top of the stove when the valve isclosed, but are depressed to open the valve when the cooking utensil isplaced over the burner. They are turned downward at their tipsto permitsliding a cooking utensil there over.

When the valve is opened it permits the gas to flow but when the weightof the cooking utensil is removed the valve is closed by means of aspring 12, thus automatically cutting off the supply of gas to theburner.

The arm 10 is made universally adjustable upon the rod by means of theuniversal joint shown in Figs. 6, 7, 8 and 9. Here the end of the arm 10is preferably of oval shape and is inclosed between the lunar shapedmembers m, m, of a collar R, forming a ball joint. This ball is inclosedin the clamping ring R integral with the depending extremity 1" of therod 8, a screw 1- serves to secure the parts rigidly together when thefingers 11, 11, are placed at the desired elevation above the burner.This elevation should be such that the weight of the cooking utensilwill depress the fingers, arm, and rod, and will rotate the valve diskto admit fuel gas to the burner the amount of opening being determinedby the amount of heat required.

The universal joint enables the arm 10 to be moved vertically to adjustthe elevations of the fingers and also to be moved longitudinally ofitself to place it in the center of the burner and accommodate itself tothe size and shape of the grating over the burner. It also permits of arotary adjustment to place the ends of the fingers which are downwardlycurved upon a common level. Other means for obtaining adjustment of thearm 10 are shown in Figs. 10, 11, 12, 13.

In Figs. 10 and 11 a connecting T-shaped sleeve T is employed to connectthe rod 8 and arm 10. Set screws 25, t, permit the parts to be securedin any desired position relative to each other.

In Figs. 12 and 13 a sleeve S upon the extremity of the rod 8 permits oflongitudinal and rotary movements only.

In further description of the valve shown in Figs. 3, 4t, 5, and 6, thecasing is shown to be divided into two cylindrical portions A and B. Theportion B is screw threaded and adjustably sleeved over the portion A.The fixed disk 7 is secured transversely in the portion 13 upon ashoulder b and the disk 6 is rotatably seated in the portion A upon ashoulder. a.

To permit the disk 6 to rotate freely with out making contact with thewall of the casing it is provided with a pivotal shaft or trunnion 16which rotates in a pivot opening 17 in the disk 7 and the disk 6 istherefore supported thereon. This structure and the shoulders preventsthe gas from passing the disks except when the perforations P come inalinement. The rod 8 is provided with a sleeve 18 which can be securedthereto at any desired angle'by means of a set screw 19 and a short arm9 upon the sleeve enters a small opening 21 formed in the inner face ofthe disk (lat a predetermined distance from the pivotal point, and thusdetermines the amount of movement of the diskwhen operated by the rod 8.

The perforations P, P in each disk are spaced apart so that they can beentirely opened and entirely closed by rotating the disk 6. a

A spring coiled within the valve chamber and engaging the disk at oneend and the wall of the chamber vat the other end returns the disk tothe closed position after the rotation of the rod 8 has opened it.

A pin X inserted in the wall of the casing A engages the slot X in thedisk 6 and limits the movement of the valve in each direction.

In Fi g. 14 the universal joint for the arm and rod is shown adaptedtothe operation of a valve V by means of an elongated finger F. Thisvalve is the one described in a prior application Ser. No. 781,112,filed July q The valve can be turned to three posi-,

tions, first, to admit gas to the burner and pilot light simultaneouslysecond, to out off the supply of gas to the burner but still supply gasto the pilot'light, and third, to cut off all passage of gas. Theseveral positions of the valve are shown in Figs. 3 8*, and 3respectively.

In Figs. 1 and 2 automatically-acting means are shown for operating theburner to close or partially close the same without removing the kettleor other cooking utensil from, the fire and thus relieve the cook fromresponsibility, and. prevent spoiling the food.

tion with a boiling-kettle and is designed to permit the kettle to riseand operate to close the valve when the water therein has evaporatedsufficiently to endanger the food therein.

In these views W is alever or beam pivoted at 'w in the top of thestove, at one side of the burner. Upon the pivotal shaft W are securedthe downwardly and curved fin- This construction is employed inconnecgers W W and upon the opposite side of the burner are secured thecorrespondingly shaped fingers W, V upon a pivotal shaft W One setoffingers W moves with the oscillation of the beam W' and the oppositeset of fingers ismoved by means of the food rests upon the upwardlyturned '8X 7 tremities. of the fingers W W it is supported thereby abovethe fingers 11, 11, but when water is added it will fall and press thefingers 11, 11 down and operate the valve to close the same, so as toprevent the food from burning in the absence of the cook, and. if asuflicient amount of water is placed in the kettle and the burnercarefully adjusted the food' can be cooked and the burner turned offwithout attention from the cook. i

H is a hook upon which the rod W" can be hung when not in use. Z I is apin upon the lever TV against which the lever VV strikes to limit itsmovement.

The valve is adapted as well as gases.
